“…Kenaf silage contained high levels of calcium and potassium. The calcium contents in Kenaf silage were much higher than the alfalfa silage, and the potassium contents of alfalfa silages were similar to values reported by Kume et al (2001). Alexopoulou et al (2013) found that addition of Kenaf leaves to other feed improved the overall calcium content.…”

The effects of harvesting stage of new Kenaf cultivars on the nutritive values, amino acid contents and fungal abundance were investigated. The late and mid-late maturing cultivars offered more DM than did early-maturing cultivars. The DM was highest at 100 DAS in all Kenaf silage. For all cultivars, the crude protein content (7.4-18.4%) of silage was reduced if harvesting was delayed. The neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents were not significantly different among the cultivars; however NDF and ADF contents increased significantly upon late harvesting. All silages had pH values under 4.0, ensuring stable storage. The optimum harvesting time for silage production, as evidenced by yield, fermentation characteristics and nutritive value, was 100 DAS. The concentrations of amino acid in the silage were lower than that in the hay. Silage produced by all Kenaf cultivars exhibited low yeast biodiversity; only one species (Pichia fermentans) was detected when the harvesting date was optimal.

“…Variation in ash and mineral concentration among crops are dependent on plant type and environmental factors (Wu et al, 2007), as well as physiological and morphological differences among plants (Hoenig et al, 1998). Interestingly, Kume et al (2001) found that CP in AF had a positive correlation with Ca, P, Mg and K.…”

a b s t r a c tCombining sweet sorghum (SS) with alfalfa (AF) for ensiling has the potential to improve the nutritive value and fermentation characteristics of resultant silages. However, the optimal combination and the associative effects of SS and AF for ensilage have not been studied. Therefore, the aim of this study was to determine the fermentation characteristic and nutritive value of silage mixtures with six different SS to AF ratios. The two forages were ensiled in air free silos for 150 days at room temperature as mixtures containing 0:100, 20:80, 40:60, 60:40, 80:20, and 100:0 of SS:AF on a fresh weight basis. As the proportion of SS increased in silage, the content of ash, crude protein, saponins, ammonia, acetic acid, propionic acid and pH decreased, while neutral detergent fiber, acid detergent fiber in organic matter, acid detergent lignin, water-soluble carbohydrate, starch, total phenolics and condensed tannins content increased. The silages were evaluated in 24-h incubations with rumen liquor. The in vitro rumen degradability of dry matter and organic matter as well as gas production, pH, ammonia, total volatile fatty acids and methane decreased as the proportion of SS increased in the silage mixtures. This study suggests that high quality silages can be made with SS:AF ratios of 20:80 and 40:60. These silage mixtures offer an opportunity to optimize the nutrient supply for ruminant production.

“…The other is to estimate the total triterpenoids content by a colorimetric method, such as the vanillin-perchloric acid spectroscopic method. However, those methods are tedious, destructive, and require severe conditions of high temperature and strong acid, not very economically viable for application in routine analyses (Kume et al, 2001;Murray & Garnsworthy, 1996). Therefore a simple, rapid, and nondestructive analytical technique to determine the content of polysaccharides and triterpenoids in G. lucidum and G. atrum is in great demand to increase their full application.…”
